Just curious.

As I know there are and can imagine there are other, "secret" facebook groups for all the pilot groups.

Rightfully so, ours was shut down due to some Diamond Platinum Status asshattery... since it is basic uncontrollable its basically recommended to not have a "secret" group as just having a secret group itself could be viewed as a possible type of work action (not my words).

Unfortunately, all the good uses are now not available...

Personally I don't think they are "secret" so much to hide it from the Company or anything, more like to keep it out of the public eye and that is just how FB works.

In other words, how do you keep a useful tool but cull the herd of asshattery?
